What This Means
This research suggests that food insecurity — not having reliable access to enough food — is strongly linked to a cluster of serious health conditions in US adults, including heart disease, diabetes, obesity, and kidney problems. Using data from nearly 14,000 adults surveyed between 2015 and 2020, researchers found that people with the lowest food security were more than three times as likely to have congestive heart failure or coronary heart disease, and more than twice as likely to have had a stroke, compared to people with full food security. Importantly, the associations followed a dose-response pattern, meaning the worse a person's food security, the higher their risk of these conditions.
The study also found that having more cardiovascular conditions at the same time was associated with greater food insecurity — people with four coexisting heart-related conditions were nearly four times as likely to experience low or very low food security. Common conditions in the sample included high rates of obesity (about 41%), elevated blood sugar (nearly 59%), and high blood pressure (about 30%), underscoring how widespread these health challenges are among US adults.
This research suggests that food insecurity is not just a social or economic issue but a significant factor tied to serious chronic diseases. Addressing food access and affordability could be an important component of efforts to reduce the burden of heart, kidney, and metabolic diseases in the United States, particularly among vulnerable populations.
